COMADMIN_E_NOUSER
COMADMIN_E_NOUSER is the failure HRESULT 0x8011040F (signed decimal -2146368497, unsigned decimal 2148598799). Its severity bit is 1, facility is 17 (FACILITY_ITF), and the facility-specific code field is 0x040F.
COM+ identity, role, and administration security: exact meaning of COMADMIN_E_NOUSER
At least one user supplied to a COM+ administration operation cannot be resolved as a valid account. User or role membership processing validates security principals against the target machine or domain.
AllStat records this condition as “One or more users are not valid”.
Evidence to collect before repair
- The result investigation needs the original account string and target computer so the exact failing boundary remains reconstructable.
- preserve SID lookup result and domain/trust status; it anchors the failure to the real administration object.
- Evidence for it should include whether the account is local, domain, managed service, or built-in, captured before a repair changes state.
- Collect the role or application identity property receiving the user when diagnosing this result; without it the symbolic HRESULT is underdetermined.
Where the result occurs
This result concerns a concrete COM+ identity, role, credential, or call-authentication contract; successful interactive access does not prove that the COMAdmin or application identity can perform the operation. In the specific case of it, log the original account string, resolved SID if any, domain reachability, trust context, and whether the account was renamed or deleted.
Diagnostic sequence
- To isolate this result, resolve the account under the target server security context.
- verify that the SID still identifies the intended principal.
- At the boundary, replace source-machine local accounts with target-appropriate identities.
- The next it diagnostic action is to apply only the failed role or identity change.
- To isolate it, repopulate the affected collection and confirm the stored SID-backed user.
Retry and recovery
Use a resolvable SID-backed principal and rerun only the failed membership change.
Practical administration scenario
A role-membership script references an account removed from Active Directory, and COM+ cannot add it.
Difference from nearby COMADMIN results
COMADMIN_E_INVALIDUSERIDS is tied to user entries carried in an application file, whereas it can arise during direct administration.
